THE RESEARCH ON SIMULATION OF WIND SPEED TIME-HISTORY OF LONG SPAN SUSPENDED DOME STRUCTURE
-
摘要: 随着大跨度空间结构的发展,风荷载对其结构的影响越来越不容被忽视。目前,国内针对这方面的研究才刚刚起步,对弦支穹顶结构的研究更是甚少。在结构的风振响应分析中,基于数值模拟方法得到的风速时程曲线被越来越多的运用。利用线性滤波器中的自回归AR模型,通过VC与Matlab的混合编程以及自行编制的Romberg积分程序,对大跨度弦支穹顶结构进行了高效快速的风速模拟,并以奥运羽毛球馆为例证明了其正确性。为后面对弦支穹顶结构的风振响应分析奠定了基础。Abstract: With the developing of long span structure,more and more attention is paid the influence of wind load on structures.At present,the domestic research on this is just started,especially for the suspended structure,the research on it is much less.The wind load based on numerical simulation methods are widely used in the structural analysis of wind-induced vibration.AR model is applied in wind speed time-history,its rapid and accurate simulation is conducted for the long span structure using mix-programming of VC and Matlab and the integral program of Romberg.Its correctness is proved by Olympic Badminton Gym.The simulation of wind speed time-history has laid a foundation for the analysis of wind-induced vibration of the suspended dome.
